Timing of motor vs ESC timing

[lasllcap@gmail.com]

what is the relationship between the “as built” motor timing ( re: Holmes Trailmaster 540 zero timing ) and the timing selection on Hobbywing ESC of 16 degrees.

how is one affected by the other ?

Is motor performance enhanced or degraded by the ESC timing choice ?

I think one is for brushed the other is for brushless.

Brushed motors get timing from twisting the can.
Brushless motors get timing from the esc.

The esc can also cheat and adjust the timing on the fly so you have more power through the rpm range. On the motor Timing is fixed.

Voodoo almost has it, but the brushless also has can timing also. Just like a brushed motor has.

Only sensored brushless. Brushless windings & magnets are fixed so only motors with movable sensor boards can have can timing. Can timing and ESC timing on a sensored motor work the same.

Sensorless timing is just the ESC predicting rotor position based on EMI feedback, and probably why some [cheaper] ESC's cog a lot more.

brushed motor timing is important, and can make or break in racing. (not so much anymore)

but brushless seems very strange. i never understood why a 3phase motor would have such adjustment. its all based off the esc (VFD/VVD) OUTPUT. Even still, most brushless motors i have (sensored) only go down to 15deg, which again, whats the point? why not go to 0. The ESC knows INSTANTLY where the rotor is it just has no clue how much power is actualy needed for movement.

one the same topic, anyone ever use or see a 6 or 8 pole 540motor (or 550) ?

wouldnt 6 or 8 pole be the ideal choice for very slow rpm and control? (more poles = larger feedback (INDUCTIVE REACTANCE CHANGE) for esc to read)

Generically speaking,
More timing = more RPM = more amperage draw (read heat)
Less Timing = more Torque

Brushed = Motor timing only.
Brushless/Sensorless = ESC timing only.
Brushless/Sensored = ESC &/or Motor timing.
